This is an interface to the reference implementation of the RFC 3797 algorithm for publicly verifiable random selection of candidates from a pool of nominees. Before the draw you will need to have notified everyone of the numbered list of nominees, and the source of data that will provide a random seed for the draw. This data should be accessible to everyone, but not until until after the list of nominees has been publicised – for example, an upcoming lottery draw, or the first paragraph from the front page of a newspaper published on the day of the draw.
